Impact of insecticides on predatory arthropods of the rice ecosystem

Abstract

                                The influence of commonly used insectides on the predatory population was studied. The results indicated that acephate, chlorpyriphos and monocrotophos were safer to Lycosa pseudoannulata, Tetragnatha javana and Paderus fuscipes while acephate, was also found to be safe to Microvelia atrolineata and Cyrtorhinus lividipennis. Phorate and carbofuran were found to be more toxic to both predators

Key words : Predators, Rice, Insecticidal effect, Lycosa pseudoannulata, Tetragnatha javana, Paderus fuscipes, Microvelia atrolineata, Cyrtohinus lividipennis
